MONTE SERENO — A day after an apparent home invasion robbery and murder shocked this quiet, tony town, police released a sketch of one of the suspects and warned that he and others were still on the loose.

Officers early Friday found on the floor of the family’s sprawling mansion the body of Raveesh Kumar Kumra, 66 — a wealthy and controversial venture capitalist who once owned the historic Mountain Winery, a popular concert venue.

Kumra, who was known as Ravi, had made — and lost — millions during a colorful career as a tech investor, most recently with Tesla Capital.

His frantic wife, Harinder, called 911 about 1:30 a.m. Friday, saying as many as four intruders had entered the couple’s 7,000-square-foot home, ransacked it and beaten her.

Harinder Kumra, who is known as Rani, was taken to a hospital, but her condition and whereabouts remained unknown Saturday.

Investigators with the Los Gatos-Monte Sereno Police Department have not revealed how her husband was killed, and the Santa Clara County Coroner’s Office declined Saturday to state the cause of death. Police spokesmen assigned to the case did not return calls requesting more information.

In a news release, police described the suspect as a skinny Latino or white man, roughly 23 to 24 years old and about 6 feet tall. He is said to have black hair and dark eyes with a light complexion.

The release added that the number of other suspects believed to be inside Kumra’s home during the crime, and their descriptions, remain unknown.

Ravi and Rani Kumra filed a petition in Superior Court in 2006 to dissolve their marriage, but they dropped legal proceedings in 2010. Ravi Kumra filed for Chapter 7 bankruptcy in 2002, and he had tax liens totaling more than $14 million filed against him by state and federal authorities in 2005 and 2010.

Kumra bought Mountain Winery in 1995 and sold it in 1998 — the same year he was arrested on charges of assaulting a security guard there and making threatening phone calls to the then-executive director of the nearby Montalvo Arts Center.

The attorney who handled his case at the time, Sam Polverino, did not return a call seeking comment.
